The device is designed based on thermoacoustic effect, Through the sound waves to achieve cooling heat dissipation of lighting equipment. The device is arranged on the main heating part of the lighting equipment. External sound waves enter the device through the resonance absorption module, and be integrated into stable acoustic frequency. Based on the thermoacoustic effect, under the effect of sound waves, the stack near one end of the sound waves form the hot end, from one end of the sound waves form the cold end, heat transfer from the hot end of the cold end to constantly. In this process, the lighting equipment heating part of the heat through the device, so as to achieve the purpose of heat dissipation.
